| 2 | Electroplastic Tensile Behavior of 5A90 Al–Li Alloys显示文摘The electroplastic(EP) tensile properties of 5A90 Al–Li alloys compared with thermal tension were investigated.The microstructural variation at different conditions was observed by SEM and TEM.The current density significantly influences the elongation and the flow stress.With increasing current density,wider and deeper dimples on the fracture surfaces and less dislocation density and pile-ups in the EP tension samples were observed compared with roomtemperature and thermal tension,which indicates the plasticity improvement and flow stress reduction.The EP effect(EPE) mainly results from a comprehensive function of Joule heating and pure EPE.Among them,Joule heating effect is perhaps a dominant factor. | Pengchao Song Xifeng Li Wei Ding Jun Chen | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，4： | 7 |
| 3 | Methodology of drug screening and target identification for new necroptosis inhibitors显示文摘Apoptosis has been considered as the only form of regulated cell death for a long time. However, a novel form of programmed cell death called necroptosis was recently reported. The process of necroptosis is regulated and plays a critical role in the occurrence and development of multiple human diseases. Thus,the study on the molecular mechanism of necroptosis and its effective inhibitors has been an attractive field for researchers. Herein, we introduce the molecular mechanism of necroptosis and focus on the literature about necroptosis drug screening in recent years. In addition, the identification of the critical drug targets of the necroptosis is also discussed. | Pengchao Pan Zhenyu Cai Chunlin Zhuang Xiaofei Chen Yifeng Chai | 2019 | Journal of Pharmaceutical Analysis2019，9，2： | 3 |
| 4 | Three-Dimensional Self-assembled Hairball-Like VS4 as High-Capacity Anodes for Sodium-Ion Batteries显示文摘Sodium-ion batteries(SIBs)are considered to be attractive candidates for large-scale energy storage systems because of their rich earth abundance and consistent performance.However,there are still challenges in developing desirable anode materials that can accommodate rapid and stable insertion/extraction of Na+and can exhibit excellent electrochemical performance.Herein,the self-assembled hairball-like VS4 as anodes of SIBs exhibits high discharge capacity(660 and 589 mAh g−1 at 1 and 3 A g−1,respectively)and excellent rate property(about 100%retention at 10 and 20 A g−1 after 1000 cycles)at room temperature.Moreover,the VS4 can also exhibit 591 mAh g−1 at 1 A g−1 after 600 cycles at 0°C.An unlike traditional mechanism of VS4 for Na+storage was proposed according to the dates of ex situ characterization,cyclic voltammetry,and electrochemical kinetic analysis.The capacities of the final stabilization stage are provided by the reactions of reversible transformation between Na2S and S,which were considered the reaction mechanisms of Na–S batteries.This work can provide a basis for the synthesis and application of sulfur-rich compounds in fields of batteries,semiconductor devices,and catalysts. | Shuangshuang Ding Bingxin Zhou Changmiao Chen Zhao Huang Pengchao Li Shuangyin Wang Guozhong Cao Ming Zhang | 2020 | Nano-Micro Letters2020，12，3： | 3 |
| 5 | Nonswellable hydrogels with robust micro/nano-structures and durable superoleophobic surfaces under seawater显示文摘Hydrogels, composed mainly of water trapped in three dimensional cross-linked polymer networks, have been widely utilized to construct underwater superoleophobic surfaces. However, the swelling nature and instability of hydrogels under complex marine environment will weaken their underwater superoleophobicity. Herein, we synthesize structured poly(2-hydroxyethylmethacrylate)(PHEMA) hydrogels by using sandpaper as templates. The robust non-swelling of PHEMA hydrogel ensures that micro/nano-structures on the surface of PHEMA hydrogels can be well maintained. Moreover, when roughness Ra of about 3~4 μm, the surface has superior oil-repellency. Additionally, even after immersing in seawater for one-month, their breaking strength and toughness can be well kept. The non-swellable hydrogels with long-term stable under seawater superoleophobicity will promote the development of robust superoleophobic materials in marine antifouling coatings,biomedical devices and oil/water separation. | Ling Lin Hui Yi Xinglin Guo Pengchao Zhang Lie Chen Dezhao Hao Shutao Wang Mingjie Liu Lei Jiang | 2018 | Science China Chemistry2018，61，1： | 3 |
| 6 | High-pressure phases of Weyl semimetals NbP, NbAs, TaP,and TaAs显示文摘In this study, we used the crystal structure search method and first-principles calculations to systematically explore the highpressure phase diagrams of the TaAs family(NbP, NbAs, TaP, and TaAs). Our calculation results show that NbAs and TaAs have similar phase diagrams, the same structural phase transition sequence I4_1 md→P6 m2→P2_1/c→Pm3 m, and slightly different transition pressures. The phase transition sequence of NbP and TaP differs somewhat from that of NbAs and TaAs, in which new structures emerge, such as the Cmcm structure in NbP and the Pmmn structure in TaP. Interestingly, we found that in the electronic structure of the high-pressure phase P6 m2-NbAs, there are coexistingWeyl points and triple degenerate points, similar to those found in high-pressure P6 m2-TaAs. | ZhaoPeng Guo PengChao Lu Tong Chen JueFei Wu Jian Sun DingYu Xing | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 2 |
| 7 | Multi-functional vesicles improve Helicobacter pylori eradication by a comprehensive strategy based on complex pathological microenvironment显示文摘Helicobacter pylori(H.pylori),creating a global infection rate over 50%,presents great challenges in clinical therapies due to its complex pathological microenvironment in vivo.To improve the eradication efficacy,herein we fabricated a pharmaceutical vesicle RHL/Cl-Ch-cal where cholesterol-PEG,calcitriol and first-line antibiotic clarithromycin were co-loaded in the rhamnolipid-composed outer lipid layer.RHL/Cl-Ch-cal could quickly penetrate through gastric mucus layer to reach H.pylori infection sites,and then effectively destroyed the architecture of H.pylori biofilms,killed dispersed H.pylori and inhibited the re-adhesion of residual bacteria(called biofilms eradication tetralogy).Moreover,RHL/Cl-Ch-cal activated the host immune response to H.pylori by replenishing cholesterol to repair lipid raft on the cell membrane of host epithelial cells.Finally,RHL/Cl-Ch-cal killed the intracellular H.pylori through recovering the lysosomal acidification and assisting degradation.In experiments,RHL/Cl-Ch-cal demonstrated prominent anti-H.pylori efficacy in the classical H.pylori-infected mice model.Therefore,the study provides a“comprehensive attack”strategy for anti-H.pylori therapies including biofilms eradication tetralogy,immune activation and intracellular bacteria killing. | Xiaonan Chen Yiqing Zou Shuqi Zhang Pengchao Fang Shuxuan Li Pengyu Li Yingying Sun Gang Yuan Haiyan Hu | 2022 | Acta Pharmaceutica Sinica B2022，12，9： | 2 |
| 8 | Development of Bioimplants with 2D, 3D, and 4D Additive Manufacturing Materials显示文摘Over the past 30 years,additive manufacturing(AM)has developed rapidly and has demonstrated great potential in biomedical applications.AM is a materials-oriented manufacturing technology,since the solidification mechanism,architecture resolution,post-treatment process,and functional application are based on the materials to be printed.However,3D printable materials are still quite limited for the fabrication of bioimplants.In this work.2D/3D AM materials for bioimplants are reviewed.Furthermore,inspired by Tai Chi,a simple yet novel soft/rigid hybrid 4D AM concept is advanced to develop complex and dynamic biological structures in the human body based on 4D printing hybrid ceramic precursor/ceramic materials that were previously developed by our group.With the development of multi-material printing technology,the development of bioimplants and soft/rigid hybrid biological structures with 2D/3D/4D AM materials can be anticipated. | Guo Liu Yunhu He Pengchao Liu Zhou Chen Xuliang Chen Lei Wan Ying Li Jian Lu | 2020 | Engineering2020，6，11： | 1 |

| 10 | Centrifuge model test on performance of thermosyphon cooled sandbags stabilizing warm oil pipeline buried in permafrost显示文摘The thaw settlement of pipeline foundation soils in response to the operation of the first China-Russia Crude Oil Pipeline along the eastern flank of the northern Da Xing'anling Mountains in Northeast China was simulated in a physical model test(with a similitude ratio of 1/73) in a geotechnical centrifuge. Two pipes of a supported and an unsupported section were evaluated over a testing period for simulating 20 years of actual pipeline operation with seasonal cyclically changing oil and ambient temperatures. The results show that pipe settlement of the supported pipe was 45% of settlement of the unsupported pipe. Settlement for the unsupported section was approximately 35% of the thaw bulb depth below the initial pipe elevation, only 30% of that for the supported pipe due to the influence of the supports. The final thaw bulbs extended approximately 3.6 and 1.6 times of the pipe diameter below the unsupported and supported pipe bottom elevations, respectively. The sandbag supports kept frozen during the test period because of cooling effect of the thermosyphons. The maximum bending stress induced over the 20 m span length from bearing of the full cover over the pipe would be equivalent to40% specified minimum yield strength(SMYS). Potential buckling of the pipe should be considered as the ground thaws.This study also offers important data for calibration and validation of numerical simulation models. | GuoYu Li HongYuan Jing Nikolay Volkov Wei Ma PengChao Chen | 2021 | Research in Cold and Arid Regions2021，13，3： | 1 |
| 11 | Occurrence Regularity and Life History of Cigarette Beetle Lasioderrma serricorne(Fabricius)in Tobacco Leaf Threshing and Redrying Workshop显示文摘[Objectives]The paper was to study the occurrence regularity and life history of cigarette beetle Lasioderrma serricorne(Fabricius)in tobacco leaf threshing and redrying workshop.[Methods]With the tobacco leaf threshing and redrying workshop as the survey site,the occurrence regularity of L.serricorne was investigated,and the life history table was inferred according to its biological characteristics.The temperature,humidity and duration of tobacco leaf threshing and redrying were simulated in the laboratory to study the survival rate of all states of L.serricorne in this environment.[Results]The lifecycle of L.serricorne in tobacco leaf threshing and redrying workshop was:the overwintering generation pupated in late February;the pupa began to emerge in early March,and reached its peak in late March.The first-generation eggs started hatching in late March,pupated in late May,emerged in early June,and reached the peak eclosion of the first-generation adults in mid-July.The second-generation eggs began to hatch in late July,pupated in mid-August,emerged in late August,and reached the peak eclosion of the second-generation adults in mid-September.The third-generation eggs began to hatch in mid-September;most of the larvae began to overwinter,some pupated in mid-November and survived the winter as pupae,and some pupae emerged to adults.The survival test results of different states of L.serricorne under simulated temperature,humidity and duration in the tobacco leaf threshing and redrying process showed that the mortality rates of eggs in simulated 1,2 and 3 conditions were about 51.22%,90.24% and 100%,and the mortalities of larvae in simulated 1,2 and 3 conditions were about 18.30%,81.25%and 100%,respectively.The mortalities of pupae in simulated 1,2 and 3 conditions were about 69.39%,100% and 100%,and the mortalities of adults in simulated 1,2 and 3 conditions were about 100%,100% and 100%,respectively.[Conclusions]L.serricorne of different states can be killed by appropriately raising the temperature during threshing and redrying. | Ding CHEN Yingjie JIANG Zijun ZHAO Chaojun LUO Xingling WANG Jie XIE Pengchao CHEN Fei XU Yongan REN Lin LU Xueqin ZHANG Shunxian LIANG | 2022 | Plant Diseases and Pests2022，13，3： | 0 |
| 12 | Composite topological nodal lines penetrating the Brillouin zone in orthorhombic AgF_(2)显示文摘It has recently been found that nonsymmorphic symmetries can bring many exotic band crossings.Here,based on symmetry analysis,we predict that materials with time-reversal symmetry in the space group of Pbca(No.61)possess rich symmetry-enforced band crossings,including nodal surfaces,fourfold degenerate nodal lines and hourglass Dirac loops,which appear in triplets as ensured by the cyclic permutation symmetry.We take Pbca AgF_(2) as an example in real systems and studied its band structures with ab initio calculations.Specifically,in the absence of spin-orbit coupling(SOC),besides the above-mentioned band degeneracies,this system features a nodal chain and a nodal armillary sphere penetrating the Brillouin zone(BZ).While with SOC,we find a new configuration of the hourglass Dirac loop/chain with the feature traversing the BZ,which originates from the splitting of a Dirac loop confined in the BZ.Furthermore,guided by the bulk-surface correspondence,we calculated the surface states to explore these bulk nodal phenomena.The evolution of these interesting nodal phenomena traversing the BZ under two specific uniaxial strains is also discussed. | Dexi Shao Huaiqiang Wang Tong Chen Pengchao Lu Qinyan Gu Li Sheng Dingyu Xing Jian Sun | 2019 | npj Computational Materials2019，，1： | 0 |

| 14 | Influence of Strain Rate on Tensile Characteristics of SUS304 Metastable Austenitic Stainless Steel显示文摘The microstructure characteristics and plastic deformation behavior of SUS304 metastable austenitic stainless steel sheets have been investigated during tensile process at diferent strain rates at room temperature.The yield stress continuously increases with strain rates due to low fraction of martensite transformed from austenite at 0.2%plastic stain.While the ultimate tensile stress(UTS)and elongation gradually decreases and then slightly increases with increase in strain rate from 0.0005 s 1to 0.1 s 1,which is attributed to the variation of the martensite fraction that is afected seriously by adiabatic heating.A higher temperature increase in the tensile specimens restricts the martensitic transformation at high strain rate.The strain rate of 0.1 s 1is considered as a transition deformation rate from quasi-static state to plastic forming,where the transformed martensitic content is very small in a higher strain rate range.Anomalous stress peaks in the later half stage of deformation occur at a very low strain rate(i.e.,0.0005 s 1)result from X-shaped strain localization repeatedly sweeping over the specimen.With increasing strain rates,the variation of dimple number density follows similar trend as that of UTS and ductility because martensite fraction mostly influences void nucleation and growth. | Xifeng LI Jun CHEN Liyan YE Wei DING Pengchao SONG | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，6： | 0 |
| 15 | Droplets deposition and harvest-aid efficacy for UAV application in arid cotton areas in Xinjiang,China显示文摘With the development of Unmanned Aerial Vehicle(UAV)sprayers,the application of low-volume spraying of harvest-aid and other agrochemicals to cotton using UAVs is becoming a new agronomic trend worldwide.The effect of spray volume and canopy density for UAV spraying is significant but was rarely studied.In this study,five representative spray volumes were explored to examine the effect of spray volume on deposition and harvest-aid efficacy for cotton using a UAV sprayer.To explore the effect of canopy density,similar tests were carried out in a field located nearby with a lower leaf area index(LAI).A conventional trailer boom sprayer was selected for comparison.Different spray volumes had a significant effect on defoliation,but had no significant effect on boll opening and fiber quality.A higher defoliation rate was achieved in the lower LAI field.The total rate of defoliation using the UAV was inferior to the boom sprayer in the high LAI field for lower deposition and defoliation rate in the lower canopy.Considering the deposition,defoliation rate,and working efficiency,a spray volume of 15.0 L/hm^(2) with an average droplet size of 150μm is recommended for UAV application. | Guobin Wang Jiahui Wang Pengchao Chen Xiaoqiang Han Shengde Chen Yubin Lan | 2022 | International Journal of Agricultural and Biological Engineering2022，15，5： | 0 |
| 16 | GEE-Based monitoring method of key management nodes in cotton production显示文摘The high-temporal-resolution monitoring of key management nodes in cotton management via agricultural remote sensing is vital forfield cotton macro-statistics,particularly for predicting cotton production and obtaining comprehensive data.This study examines Shihezi,Xinjiang as a case study,utilizing Sentinel-1 and Sentinel-2 data from 2019 to 2021.Three machine learning models(RF,SVM,and CART)were employed to extract annual crop classification area rasters,monitor weekly cultivation progress,and monitor abandoned cropland during the cultivation period.The results demonstrate that the random forest model has produced satisfactory results in gridded extraction for cotton classification areas,achieving the producer’s accuracy of the cotton category reached 98.5%,and the kappa coefficient is 0.947.Cotton cultivated in 2021 began is a week later than in 2020,yet exhibited a faster cultivate speed.The proportion of abandoned cottonfields in the study area rose in 2020 compared to 2019.The methodology presented in this study has a certain reference value for exploring the monitoring of continuous changes in crops over the years and macro-monitoring of important activities in the entire growth cycle. | Weiguang Yang Weicheng Xu Kangtin Yan Zongyin Cui Pengchao Chen Lei Zhang Yubin Lan | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 17 | Application of heat-activated peroxydisulfate process for the chemical cleaning of fouled ultrafiltration membranes显示文摘Na Cl O has been widely used to restore membrane flux in practical membrane cleaning processes,which would induce the formation of toxic halogenated byproducts.In this study,we proposed a novel heatactivated peroxydisulfate(heat/PDS)process to clean the membrane fouling derived from humic acid(HA).The results show that the combination of heat and PDS can achieve almost 100%recovery of permeate flux after soaking the HA-fouled membrane in 1 mmol/L PDS solution at 50℃ for 2 h,which is attributed to the changes of HA structure and enhanced detachment of foulants from membranes.The properties of different treated membranes are characterized by scanning electron microscopy(SEM),atomic force microscope(AFM),attenuated total reflection Fourier transform infrared spectroscopy(ATRFTIR),and X-ray photoelectron spectroscopy(XPS),demonstrating that the reversible and irreversible foulants could be effectively removed by heat/PDS cleaning.The filtration process and fouling mechanism of the cleaned membrane were close to that of the virgin membrane,illustrating the good reusability of the cleaned membrane.Additionally,heat/PDS which can avoid the generation of halogenated byproducts shows comparable performance to Na Cl O on membrane cleaning and high performance for the removal of fouling caused by sodium alginate(SA),HA-bovine serum albumin(BSA)-SA mixture and algae,further suggesting that heat/PDS would be a potential alternative for membrane cleaning in practical application. | Jiaqi Ding Haoliang Xiao Xiaolong Huang Yujia Zou Zhimin Ye Songlin Wang Pengchao Xie Yongsheng Chen Jun Ma | 2023 | Chinese Chemical Letters2023，34，10： | 0 |
| 18 | Unveiling the charge density wave inhomogeneity and pseudogap state in 1T-TiSe_2显示文摘By using scanning tunneling microscopy(STM)/spectroscopy(STS), we systematically characterize the electronic structure of lightly doped 1 T-TiSe_2, and demonstrate the existence of the electronic inhomogeneity and the pseudogap state. It is found that the intercalation induced lattice distortion impacts the local band structure and reduce the size of the charge density wave(CDW) gap with the persisted 2 × 2 spatial modulation. On the other hand, the delocalized doping electrons promote the formation of pseudogap. Domination by either of the two effects results in the separation of two characteristic regions in real space, exhibiting rather different electronic structures. Further doping electrons to the surface confirms that the pseudogap may be the precursor for the superconducting gap. This study suggests that the competition of local lattice distortion and the delocalized doping effect contribute to the complicated relationship between charge density wave and superconductivity for intercalated 1 T-TiSe_2. | Kai-Wen Zhang Chao-Long Yang Bin Lei Pengchao Lu Xiang-Bing Li Zhen-Yu Jia Ye-Heng Song Jian Sun Xianhui Chen Jian-Xin Li Shao-Chun Li | 2018 | Science Bulletin2018，63，7： | 0 |
